Problems solved by technology

The inventors of this application found that the existing passive indoor distribution system is mainly aimed at 2G, 3G, and 4G frequency bands, but there is a problem of large loss in the higher frequency bands of 5G
[0004] On the other hand, in the existing technology, the active digital indoor distribution system based on the micro base station has defects such as large system scale, high cost, and large power consumption requirements.

Abstract

The invention relates to a method for a wireless communication signal distribution system, and the method comprises the steps of: obtaining a first I / Q baseband signal; performing quadrature modulation on the first I / Q baseband signal to obtain a second modulation signal; transmitting the second modulation signal through a twisted pair channel; receiving the second modulation signal from the twisted pair channel; and orthogonally demodulating the second modulation signal to obtain the first I / Q baseband signal.

Description

Technical field [0001] This application belongs to the field of mobile communication, and in particular relates to a method for a wireless communication signal distribution system, an orthogonal frequency shifter, an access unit, a radio frequency unit, and a wireless communication signal distribution system. Background technique [0002] It is estimated that 70% of the data traffic and services of 5G communication will occur in indoor scenes, such as stations, airports, stadiums, hospitals, subways, shopping malls, hotels, office buildings, etc. In addition, 80% of 5G communication users' working hours will be in an indoor environment. The main frequency bands of 5G in China are 2.6GHz and 3.5GHz, which are higher than the mainstream frequency bands of 2G, 3G and 4G, and the transmission loss and penetration loss are increased, making it difficult to cover indoors through outdoor. The signal coverage of 5G signals is the key to 5G services. [0003] Based on the existing passive...
